From time to time I've toyed with loading up modified firmware onto my Linksys WRT-54G v2 router but I've never actually done it. I doubt it's that big of a deal to install but after looking over the various modified firmware distributions out there I'm not sure if its really worth it. Do any of the distributions that are out there actually improve on the routing performance of this router or do they all just add on additional features like VPN?
